Liver Pathology / Vascular Abnormalities Of The Liver Part 2

___________ syndrome is caused by thrombosis of the main hepatic veins.

Put the following stages of portal vein thrombosis in order as they appear sonographically:1. cavernous transformation of the portal vein2. when thrombus is fresh it appears anechoic, making it hard to visualize3. thrombus becomes more echogenic and there is a dilation of the PV at and proximal to the thrombus or occlusion

With Budd-Chiari syndrome, hepatic veins may appear anechoic to __________ depending on the stage of thrombus.

Thrombus/tumor must be visualized within the lumen in order to make the diagnosis.

• True

• False

Check all that apply to the clinical and lab data of Budd-Chiari Syndrome:

• Ascites

• RUQ pain

• Jaundice

• Hepatosplenomegaly

Check all of the following that apply to the causes of portal vein thrombosis in infants:

• Sepsis

• Umbilical vein catherization

• Acute dehydration

Sonographic appearance of Budd-Chiari syndrome depends on the degree of venous ________ and the underlying cause.

The caudate lobe is often ______ in Budd-Chiari syndrome.  The _____ veins drain directly into the IVC at the level lower than the main hepatic veins.  The increased blood flow through the caudate lobe leads to caudate __________ or hypertrophy.

Check all that apply to the etiology of Budd-Chiaris syndrome:

• Tumor invasion

• Pregnancy

• Oral contraceptives

• Mechanical compression from liver tumor or cirrhosis

• Hypercoagulation states

Check all that apply to the sono appearance of Budd-Chiari syndrome:

• Ascites

• Splenomegaly

• Hepatomegaly

• Dilation of the HV at and proximal to the thrombus or occlusion

• Intrahepatic collaterals or hepatofugal flow in the branches of the PV

Check all that apply to the clinical and lab data of portal vein thrombosis:

• Abdominal pain

• Hypovolemia

• Fever

• Leukocytosis

• Hepatomegaly
